Chilled Water Pipe Insulation Thickness Calculation Formula

Extra margin must be taken on insulation thickness as sometimes conducting heat transfer through insulation may become higher than convective heat transfer due to air on outside wall of insulation.

Chilled water pipe insulation thickness calculation formula.

Indoor chilled water cooling and chilled water insulation ducting renovation expansion new construction insulation. Heating cooling pro standard. The calculator is generic and can be used for both si and imperial units as long as the use of units are consistent. 2 0 role of pipe insulation for chilled water systems 33 f to 60 f 0 5 c to 15 6 c pipe insulation for chilled water systems is specified and installed primarily for process control condensation control and energy conservation.

Hence insulation thickness ri rp 0 2302 0 1524 0 0777. Calculate insulation thickness minimum value required for a pipe carrying steam at 180 0 c. Insulation thickness 77 7 mm. The heat loss from steam per meter of pipe length has to be.

For below ambient service by contrast the new pipe insulation thicknesses are not particularly noteworthy. When piping and equipment. The pipe size is 8 and the maximum allowable temperature of outer wall of insulation is 50 0 c. Cooling and heating load excel sheets free excel sheet for calculating pipe insulation thickness.

Chilled water pipes emit heat all the time so they must be insulated and this excel sheet calculates heat loss and insulation thickness. D o outside diameter m in d i inside diameter m in ρ m density of piping material kg m 3 lb in 3. Industrial insulation phase 2 8 insulation thickness thermal conductivity performance criteria revision 2 0 august 2014 3 0 calculation of material thickness to achieve heat loss values 3 1 heat loss calculations pipe insulation is thermal insulation used to prevent heat loss and gain from. For example 1 in.

Is sufficient thickness for all sizes on chilled water lines with an assumed operating temperature in the 40 f to 60 f range. This calculator can be used to calculate the weight of a pipe with or without liquid. Insulating chilled water systems requires special attention. Thermal conductivity of the insulation material for the temperature range of the pipe can be taken as 0 04 w m k.
